Detailed Description

When destroyed, it makes sure that all the tasks spawned by the current thread since its creation have finished.

A typical pattern of use for an Observer is

{ Observer o;
  spawn(...);
  spawn(...);
}

which makes sure that the two spawned tasks have finished before leaving the block.
